Chevrolet Impala Rear Door Panel Speaker Size
The Chevrolet Impala rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. The specifications cover a range of years from 2014 to 2020.
| Year | Type | Size (inch) |
|---|---|---|
| 2020 | Midbass / Full-Range | 6.5 |
| 2019 | Midbass / Full-Range | 6.5 |
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The rear door panel location in the Chevrolet Impala positions speakers within the lower portion of the passenger cabin doors, where the driver cone faces inward toward the seating area at roughly seat-level height.
- Door panel mounting places speakers in an enclosure formed by the door cavity itself, which acts as a partial acoustic chamber behind the driver cone.
- A 6.5 inch driver diameter falls within the mid-woofer range, giving the cone sufficient surface area to move air for frequencies typically spanning from around 50 Hz up through 5 kHz depending on the driver's construction.
- At the rear door panel location, a 6.5 inch driver is positioned toward the rear of the listening environment, which affects the spatial contribution of lower midrange and bass frequencies reaching front-seat occupants.
- The Chevrolet Impala rear door panel accommodates a 6.5 inch mounting diameter across the 2014 through 2020 model years, establishing a consistent cutout and depth requirement for replacement drivers.
- A midbass driver is designed to handle the lower portion of the midrange and upper bass frequencies, typically operating below the range where a tweeter takes over, and is not intended to reproduce the full audible spectrum on its own.
- A full-range driver is constructed to reproduce a wider portion of the audible frequency spectrum from a single cone, covering bass, midrange, and a degree of high-frequency content within the limits of the cone size.
- In a rear door panel location, a midbass driver contributes low-mid frequency body and warmth to the overall system, often working alongside dedicated tweeters mounted elsewhere in the vehicle.
- When a full-range driver is installed in the rear door panel position, the 6.5 inch cone handles bass and midrange content while also attempting to reproduce higher frequencies, though the large cone diameter introduces some directional dispersion narrowing at higher frequencies.
- Door panel installations require attention to mounting depth, as the inner door structure limits how far a speaker basket can extend behind the mounting surface before contacting window mechanisms or structural components.
